Multiplayer Speed Problems

Multiplayer Speed Problems

I'm having a lot of trouble with the old multiplayer-speed-up problem that's supposedly a lag fix. The game runs super fast (3+ times the speed that it should) for 10-20 mins after starting a new multiplayer game, or reloading a save. It's rough and no fun in the beginning of multiplayer games, and makes the game absolutely unplayable when trying to play mid/end-game from a loaded save.

We are currently playing on just two computers that are on the same network. After this lag "fix" stops doing its thing and the game speed reverts to normal, there is never any lag. The problem only occurs for 10-20 minutes at the beginning/after loading a save, never in the middle of a game. My conclusion is that this feature has become purely a bug.

Is this a common thing that a lot of other people have experienced? Is there a fix or a way to turn off this "feature"? I'd appreciate any help; it's really ruining my Sins experience. Thanks!
